Hi,
I am trying to solve the following differential equation:
DSolve[y''[x] == -y[x]^2 Cos[x], y[x], x]
Mathematica 6.0 for Linux x86 (64-bit) gives me a solution involving
the WeierstrassP function. It is easy to check that the given solution
is wrong (just substitute back into the differential equation and plot
for some random coefficients C[1] and C[2]).
(1) Can you help me solve this equation?
(2) Is this a bug in Mathematica?
Thanks!
Roman.
